Back and forth she goes
Rocking back and forth
Gliding back and forth
Bit o' the old back-and-forth
rocking back and forth
back and forth
Back and forth
Back-and-forth!
Back and Forth Forever
Back and forth
Back & Forth
I whip my dick back and forth
Pulling it back and forth
Back and forth
Back and forth
Up and down, back and forth
